I meant to be observed it again but because of problem described below, ran out of time. Yale Magnitudes: Cen X-4 0.37 xte1550 8.7 4u1543 1.32 Aql X-1 *see note *Technical problem caused extremely elongated CCD images during Aql. The culprit would be the DTI unit (guiding system), the wich it froze, my guess id after I started guiding. e.i.; it looked as if it was guiding but it really was not. ------------------------------ Submitted by Juan Espinoza on 2001 Jun 3 [7:19:56]
